    Confused start & run capacitors

    Does it matter if you change a compactior (start) with a run compactior?
    I have gone into to the supplier to find only run compactiors, and I would like to know does it matter.
    Thank You

    Yes, it does matter. They are not the same.

    We usually dicuss technical topics in the pro residential forum.

    Pros should post their technical questions there, or in pro commercial, as is appropriate.

    Start caps and run caps might seem like they are similar, but they are very different. If you swap them around you might end up damaging a motor.

    Is 'compacitor' what you do to repair a swelled capacitor? Do you use a capacitor compactor?

    Has anyone noticed a pattern in the types of capacitors that are failing prematurely? I changed a 60 MFD @370 run capacitor on a compressor 4 ton. It was drawing 21.7 amps. With new capacitor the amp draw dropped to 14.1. In the last 10 years I have changed 5 times as many capacitors as I did in the 90's.

    It's just like everything else, made cheaper to keep the share holders wallets fat.

    That's funny. Just the idea of a shareholder with a "fat wallet."

    I think you should be on Leno.

    Never seen leno, just facing the facts. Even the almighty trane has been outsourced to China and skimped to the point that its like the rest of the garbage. I'll leave the politics to leno... Just want a good product that will last and is worth the cost and capacitors doesn't fall in that slim category.

    I think it may be because of the somewhat new regulations in the types of chemicals that can be used inside. The older stuff is a lot more nasty than the newer stuff. I am thinking that the newer stuff may make it easier to fail though. Either that or it is because they are made by China these days which makes crap. And everything is made to fail these days. even stuff that used to be made to last.

    The icing on the cake is that that the US has to borrow money from China(the country we outsourced our jobs, products, and even resources to) in order to keep dysfunctionally, functioning. The thought process doesn't make a bit of sense. Not to be a conspiratist, but i'd imagine that the money and politics is not what it seems, there's a black market shuffle involved somewhere. Call it a reasoned rant...

    Last week I replaced an evaporator fan motor in an ancient looking reach in freezer. It was an old GE motor, made in the USA. The replacement I got from Meiers' was also a GE only it was made in China. It failed after less than a week. May have been a coincidence but I'm more inclined to think the 12 year olds making $2/hr and working 15 hour days are slacking.
